- Adding parsing logic in mappers/reducers is the simplest, least elegant
way to do it, or just writing json strings is one simple way to do it.
- You get more advanced by writing custom writables which parse the data
are the first way to do it.
- The truly portable and "right" way is to do it is to define a schema and
use Avro to parse it. Unlike manually adding parsing to app logic, or
adding json deser to your mapper/reducers, proper Avro serialization has
the benefit of increasing performance and app portability while also code
more maintainable (it interoperates with pure java domain objects)
